I've got a 2001 New Beetle. With the back seat down, it's a perfect fit for my 4-pc (w/24" kick) plus hardware and cymbal bags.

However, I recently have discovered that the Turbo Beetle with the 1.8T engine, like I have, has a horrible problem with sludge buildup that (sooner than later it seems!) kills the engine, and that my car is running on borrowed time! So, first thing next year, I will be trading in the Beetle for whatever I can get before it dies, and shopping around for a replacement.
